New research points to a biological difference in breast cancer tumors among African American and Caucasian women.
In a new study researchers from the National Cancer Institute compared the genes in breast tumor samples from both races. They found the tumors were different in many ways, including how the cells interact with the immune system and their growth.
In general African American women have more aggressive breast cancers.
According to the press release, researchers say the data indicates inflammation and immune system response play a stronger role in the development and progression of cancer in African American women.
